Radical polymerization of methyl methacrylate (MMA) initiated with organic pero-xide-ditertiary amine binary systems was studied in this paper. In order to study the effects of organic peroxide and amine respectively

benzoyl peroxide (BPO)

lauroyl peroxide (LPO)

t-butyl hydroperoxide (TBH)

and t-butyl peroxybenzoate (TBPB) were used as organic peroxide component

and aromatic ditertiary amine 4

4'-tetramethyldia-minodiphenylmethane (TMDAPM)

and aliphatic ditertiary amine tetramethylethylene-diamine (TMEDA) were used as amine component. It was found that in the bulk poly-merization of MMA using organuc peroxide-TMDAPM binary initiation systems

the ef-fect of organic peroxide on the polymerization rate of MMA Rp was in the following order:BPO>LPO>TBH>TBPB. However

in the organic peroxide-TMEDA binary systems

the order of Rp was LPO-TMEDA>TBH-TMEDA

and BPO-TMEDA

TBPB-TMEDA system could not initiate MMA polymerization. The values of Ea

overall activation energa of polymerization

of MMA initiated with organic peroxide-TMDAPM systems were determined. According to the kinetic studies of MMA polymerization initiated with BPO-TMDAPM

LPO-TMDAPM system

the foll-owing equations were obtained.
